Required Tools 
Tool  Part Number  Part Name  Qty 
A(1)  9U-6198  Crankshaft Turning Tool 
A(2)  9U-7336  Housing 
5P-7305 Engine Turning Tool 
(1) The Crankshaft Turning Tool is used on the front pulley.
(2) This Tool is used in the aperture for the electric starting motor.

Start By:

  1. Remove the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Remove".

Note: Either Tooling (A) can be used. Use the Tooling that is most suitable.


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


  1. If the crankshaft is installed, use Tooling (A) to rotate the crankshaft in order to gain access to the piston cooling jet.

  1. Clean the piston cooling jets and inspect the piston cooling jets for damage. Ensure that the valve is free to move within each piston cooling jet. Replace any damaged piston cooling jets. The procedure for checking the alignment of the piston cooling jets is described in Specifications, "Piston Cooling Jet Alignment".

  2. If the crankshaft is installed, use Tooling (A) to rotate the crankshaft in order to access the mounting flange for the piston cooling jet.

  3. Position piston cooling jet (2) in the cylinder block. Install bolt (1). Tighten bolt (1) to a torque of 9 N·m (80 lb in).

  4. Repeat steps 2 through 3 for the remaining piston cooling jets.

End By:

  1. Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
